4-Aminodiphenylamine diazonium sulfate 4-Diazodiphenylamine sulfate 4477-28-5 Azoic Diazo Component 22 Azoic Diazo No. 22 MFCD00011895 Variamine Blue RT salt (CAS 4477-28-5), molecular formula C12H22N3HO4S and molecular weight 305.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Aminodiphenylamine diazonium sulfate 4-Diazodiphenylamine sulfate 4477-28-5 Azoic Diazo Component 22 Azoic Diazo No. 22 MFCD00011895 Variamine Blue RT salt (C12H22N3HO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 305.39 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
